Grammar:
（一）祈使句
1.定义
用于表达命令、请求、劝告、警告、禁止等的句子叫做祈使句。祈使句的动词都为一般现在时，句末则使用句号或感叹号。
2.构成：Please在句首不加逗号，在句末时前面加逗号。

(2)Be型(以be动词开头)
(肯) Be polite! (否) Don’t be late.
(3) Let型
(肯) Let sb do sth (否) Don’t let sb do sth. / Let sb not do sth.
(4)与if条件句转换：If you try your best, you won’t lose the match.

(2) Fix the bookshelf for me,please.(祈使句)

3.反意疑问句
定义：表示提问人的看法，没有把握，需要对方的证实。
结构：一个陈述句 + 一个简短的疑问句
注意：两部分的人称和时态要保持一致
（1）Let’s表示第一人称的祈使句，反意疑问部分为“shall we”。
如： Let’s go to the park, shall we?
（2）Let me和Let us表示第二人称的祈使句，反意疑问部分为“will you”。
如： Let me have a look, will you?
（3）其他行为动词引起的祈使句，无论其陈述部分是否定还是肯定的，多用“will”。
如： Don’t be late again, will you?
以上三种反意疑问句的回答：肯定回答：Yes, I will.
否定回答：No, I won’t.

（2）情态动词should和had better
1.should的用法，后接动词原形。
（1）表示“应该，应当”。
如：He should work harder. 他应该更努力地工作。
（2）表示猜测，意为“可能”。
如：His friend should be in the classroom.他的朋友可能在教室里。
2.had better的用法
（1）had better的基本用法：意为“最好” “应该”，后接动词原形，其中的had通常缩略为 ’d。
如：You had better work hard. = You’d better work hard. 你最好努力学习。
（2）had better如何构成否定式和疑问式构成否定句时，通常将not置于had better之后（而不是had之后）；而构成疑问句时，则通常将had（而不是had better）置于主语之前。
如：You had better not be late again. 你最好不要再迟到了。

3.两个词的区别
用法相似，但had better在语气上比should更强力。
